Nymph

Nymph is an "Electronic Warfare Angeloid, Type Beta" (電子戦用エンジェロイドタイプβ（ベータ）) who mysteriously appears in Tomoki's house. She is condescending toward humans, whom she refers to as "bugs". She weighs 29 kilograms and is 139 centimeters tall. Her wing type is listed as "Not Variable" and "Stealth". Nymph can completely conceal her wings, unlike Ikaros, who can only retract her wings to a certain point. She was originally sent to return Ikaros to Synapse. However, because she is less powerful than Ikaros, she was unable to do so. Her master later implanted a bomb within her collar, designed to explode after the green bars on it disappear, which was later disabled with help of Tomoki and his friends. She soon develops feelings for Tomoki and later confesses to him. After the Gamma Angeloids attempt to kill her, she betrays Synapse and assists Tomoki, later moving into his home. Her wings were torn off by the Harpy Angeloids, but they regrow when she accepts Tomoki as her new master. However, in her delight at having her wings regrown, she forgets about the imprinting process and finds it extremely difficult to broach the subject to Tomoki. By her own admission, it is not a difficult task, but she feels embarrassed enough to eventually back out of asking. Eventually, Nymph asks Tomoki to allow her to Imprint on him, but he refuses, saying that he wants her to live freely. She is named and modeled after the nature spirits of Greek myth.

As an Electronic Warfare-type Angeloid, she has the ability to hack computer systems better than any other Angeloid. She is also capable of hacking other Angeloids as well as humans (Blocking or Unblocking memories and abilities). She can also fire a high-powered energy beam from her mouth called "Paradise Song" (パラダイスソング Paradaisu Songu). When being hacked by Hiyori, Nymph displays a new ability, a "fundamental particle-jamming system" called Aphrodite (アフロディーテ Afurodīte). When she is using it, she becomes immune to hacking and her wings grow into a butterfly shape. However, using it generates a lot of heat, causing her to enter cooling mode as a result. Nymph has high processing capabilities and has high emotional control, but as a result she doesn't have much raw power. She also has the most powerful radar of the three first-generation Angeloids (Ikaros has stated that her own radar's proficiency cannot be compared with that of Nymph even though Nymph was wingless at that time and stated that her radar was a lot weaker ever since her wings were torn off.) Nymph is shown to have a sweet tooth; her appearances mostly show her snacking on chips and other snacks, and she is shown to have a penchant for watching soap operas. She refers to the other Angeloids by their types rather than their names (i.e. Ikaros→Alpha). She is also an intellectual genius.
